This self-cleaning litter box eliminates most odors while keeping the litter pleasingly fresh for sammy the cat.

It’s ingenious in design: a cat entering the box triggers a sensor; the sensor sets a timer that counts off 10 minutes; then a rake runs through the litter.

Scooping out clumps and depositing them in a plastic container at the box’s end; the container is automatically sealed until the next cat visit, when the raking cycle opens the container for another deposit.
